Actually the Audi 2.7T also has an after-run electric coolant
pump that circulates coolant through the system and runs
the electric radiator fan.  It is not timer driven, but temperature
driven.  I think the thermoswitch that activates this system has
a temperature threshold that is wayyyy-high.  I don't think I've
ever heard mine come on.
